#TradingPairs101 Trading pairs in cryptocurrency or traditional markets refer to two assets that can be exchanged for each other on an exchange. They are quoted as Asset A/Asset B, where Asset A is the base currency (what you're buying or selling), and Asset B is the quote currency (what you're paying or receiving). For example, in the BTC/USD pair, Bitcoin (BTC) is traded against U.S. dollars (USD). The price indicates how much of the quote currency is needed to purchase one unit of the base currency. Trading pairs are vital for determining an asset’s value relative to another and enable arbitrage opportunities.
